Description

technical field

[0001] The invention relates to the field of welding electrodes, in particular to a cooling system for a special welding device for projection welding nuts. Background technique

[0002] In the field of auto parts manufacturing, a large number of parts have projection weld nuts. The projection welding nut process is to place the nut with bumps on the thin plate parts to be welded with it, and use the lower electrode to position it, and press it on the projection welding nut through the downward movement of the upper electrode, so as to realize the alignment between the bumps under the nut and the thin plate parts. The connection is soldered.

[0003] In modern industrial welding technology, the projection welding process accounts for a large proportion. The projection welding process usually uses a high-density welding current to achieve the effect of metal melting and connection under the action of external force through the limited contact area between pa...
